How to choose
Match tank size to run time
Tank size runs from 1.5L on the Pure Enrichment to 2.5L on the LasVacde and Bear, with the Fontaines at 2L. Tank size and run time do not move together here: the 2L Fontaines runs 33 hours while the 2.5L Bear runs 25 hours, and the 1.5L Pure Enrichment also runs 25 hours. Compare both figures for each pick instead of assuming one predicts the other, and check the setting, since high and low settings change the hours.
Compare coverage by maker figure
Coverage is the maker's own figure, so read it as a guide and compare it with your room size. The Pure Enrichment is rated for up to 250 sq ft by the maker, the LasVacde is rated for up to 320 sq ft by the maker, and the Fontaines is rated for up to 247.5 sq ft by the maker. Pick the figure that fits your room, then weigh tank size and run time.
Check cleaning and night lights
Cleaning differs across these picks: the Fontaines top-fill opening gives easy access for cleaning, the LasVacde parts come apart for cleaning, and the Pure Enrichment comes with a disk cleaning brush. Night lights also differ: the Pure Enrichment, LasVacde, and Fontaines each have one. Check which cleaning style and light fit your routine before you pick.
